by:

These jacks are quality built and held up for a 3 month trip to Alaska. I choose to weld the two halves together to minimize the offset. The heavy material made it easy and very sturdy. The system is powerful enough to lift rear of our RV unit partially off the ground but you need to be careful to support the axles so you don't twist the frame on light trailers.



by:

Very pleased. Not that hard to install. These replace the weak stabilizers that came with the trailer. You'll need a jack and an electrical kit to complete the install.

Still working just fine, Ive suggested it to anyone who askes about it.



by:

I ordered 2 of these units. I give UPS 1 star because they lost an entire unit so I called etrailer and I give them 5 stars for immediately shipping a third unit. Then the first unit arrived from UPS and they lost the motors and hardware kit. I called etrailer and they are shipping more motors and the hardware kit. Hoping UPS doesn’t lose the parts for the replacements! The photo shows all I received so far for two full kits.



by:

Installed on a 2018 E350 Ford Minnie Winnie. The package arrived really beat up but only a single cover was damaged. It was replaced quickly. Nothing was missing.

I had to shim it down from the frame about 1.5 inches using a bar of 1.5"x3"x 24" inch aluminum stock on each side. Then it would clear the fuel tank and the gray water.

Switches are installed in our garage under the bed. Wiring came from power panel which is fairly close to the switches so it all went fairly well. Wire nuts are not recommended so I had to hunt around to find connectors that would work.

I have not used it for camping so do not how well it will work to stabilize the vehicle. We do a lot of boon docking so will have to have some good blocking to level and stabilize. It feels a little better sitting on the street. I do wish there was a lockout for them being raised before moving the vehicle outside of PARK?

After a year of use, they make a huge difference when parked overnight.



by:

I got the jack for three reasons. My original jack was intermittent, it was bent and it did not level the trailer because it had only one motor. The new jack works great and it can level the trailer because it has two motors and the power required. It was not the easiest to install because of the increased size and it will not level the trailer if it is off more that 2 inches or so side to side. In spite of these drawbacks and the fact it added weight to the rear of the trailer I am very happy with the new jack.

Good. Only issue I have is it is slower than my old jack



by:

Your going to love this product. I was able to fit on to a 1987 Avion travel trailer I renovated for my sister (spectacular renovation). It made the camper rock solid. You can't feel anybody walking around, no high wind movement. It felt like we set it on a concrete foundation. It is a well designed product I will use in the future if I renovate another classic beauty, even my own every day travel trailer.

Great product.

Excellent product



by:

Scary at first, but following directions, it bolted right onto the frame, used a floor jack to hold it in place while attaching. Wiring was uncomplicated, except for figuring out where to route the wires. works fine, I am a happy camper!

still works great.

I was very satisfied with the excellent service I received. Rose was very helpful. Box was a little tattered but all parts were intact. I installed stabilizers and they work as expected .Very easy to install as I did them myself

They are working great just as u expected very good product. Would recommend to anyone. Thanks Again to Rose for her help

Installation was easy, need a helper just to make it safer. CSR people are great very helpful!! Works as promoted and I have recommended this product to other campers.

Well after 1 year of use the Jacks are still doing very well we have gone on at least a dozen trips that they have been utilized. I am very glad to have purchase them, the installation was very easy great videos!! Best Regards P.S I have recommended to other campers and have even assisted on installing them.



by:

i find these easy to operate. installation took a little time as i had to works underneath the camper. i have discovered, the middle of the jacks flex when leveling. i have some heavy angle iron, i am going to reinforce them. before i do that operation, i am going to add more bolts, that may be the simple solution.

overall, excellent product.



by:

On my 5 whl the landing gears froze up and would not turn either way. I ordered LC179013 and installed myself. That was s good job for an old 70Yrs fat man to do..
I got them installed and wired up and they work like a champ. That has been over a year ago and have been used alot.



by:

I purchased 4 sets of these for 2 trailers. One motor intermittently will not run unless I remove the cover and turn it by hand. It occurred immediately after installation. Should have returned it.



by:

The product itself is a good product but the packaging for shipment is very bad. I received mine and the box was badly torn apart and tapped back together. I was missing multiple pieces and had to wait until the replacement pieces arrived. Customer service was very helpful with resolving this problem within minutes.



by:

Exact replacement of what was on the Carrilite 5'er with both products, the levelers and the front landing gear.
Fast efficient service as usual!



by:

The product does what we needed it to d o.

Finally got around to installing my PT II Stabilizers 30" front and rear of our 26' Surveyor. Pre - assembled them to make sure they went together ok. Luckily I had two sources for power front & rear which made wiring easy, I used a Buss block to make all positive connections, grounds straight to frame, soldered all connections and heat srinked to seal. Using the 3/8" self tappers was fun.Well got it all together and all works well makes trailer very stable, don't have to worry about scissor jacks collapsing anymore.



by:

It looks like a great product am anxious to install them.
I have a symbol of them in my garage and I have one with a really crooked foot. The bolt hole on the retracting arm was drilled in the wrong place so it is totally crooked, not a deal breaker though. I’m sure the are more than Adequate



by:

I finished the assembly and install of the power twin II stabilizer and have included pictures of the install. This is a good quality unit and I am very happy with how it works.

by:

Would have been nice to know that it didn't fit my Grand Design Imagine 22MLE without some "frame modifications", and over $xxxx in installation costs.

Warning to new buyers; DO SOME REAL CLOSE MEASURING TO MAKE SURE THE SYSTEM
WILL FIT BETWEEN ALL ATTACHED HARDWARE, LIKE DUMP VALVES AND DROP FRAMES! any modifications will cost you dearly.

Electric motors are very slow, seems like it takes forever to drop each foot.

BUT----------They do work.



by:

After installation the stability or my toy hauler was increased X3. The installation was relatively easy and all that was needed was common tools and a floor jack. Wiring was covered by simple easy to follow instruction. Some shrink wrap and a solder gun make permanent water resistant connections which I recommend.



by:

If you are looking for "stabilizers" that are strong enough to handle heavy trailers this is the unit for you. A little inconvenient because of the independent screws but they will lift the weight indicated which is why the stabilizers are in quotations.



by:

Little intimidating at first, just took my time and it went together without any major problem. The problem that I had was dealt with quickly. It's solid and well built. Print on the instructions was a little small for my eyes. Having the instructions on line was a great help.



by:

The Jacks are considerably more durable well built compared to the Lippert models. The lifting power is real and once on the ground the prevent movement of the RV by orders of magnitude over the other style jacks. I only have one in the center of a long trailer and it has stopped the bouncing and side to side swaying of the trailer. Just stepping onto the stairs to get in its rock solid. Also when all the legs are deployed the doors close way better than they ever had with just the Lippert jacks on the front and back. Definitely recommend to anyone thinking about a better jack than what's provided oem.



by:

This product is awesome and has made a substantial difference in the stability of our camper! We have a 32' travel trailer and the factory jacks are sad and could feel every movement of the kids. This has taken away 90% of the movement that we were having before.
If you are not handy plan on having someone install this for you. It's not hard to do but if you don't have some tools for the job you will struggle. It took about 4 hours total to install.

  • How Many Jacks Come With The Ultra-Fab Twin Electric Stabilizer
    Hey, that's a great question. Ultra-Fab Power Twin II Electric Stabilizer for Trailers and RVs - 22" Lift - 6,000 lbs # UF39-941707. The picture on our site is what you will get. So to break it down, if you hit quantity ONE you will get the unit with two feet that looks like it is bolted together. It will come with two legs.

  • Replacement Stabilizer Jack System for 2021 Jayco Jay Flight Travel Trailer
    The best option from Lippert is the Lippert High-Speed Power Stabilizer Jack, # LC298707. But in this style of stabilizers, I prefer the Ultra-Fab products, they have the Power Twin II Electric Stabilizers with Dual Motors, use # UF39-941705 for a 30" lift and # UF39-941707 for 22". See the product pages for specs and application of which is best for your trailers frame width and spacing. The Ultra-Fab Power Twin II has dual 12V motors that function independently for quick, simple leveling....

  • Stabilizer that Can be Used on 2022 Jayco 24LP Motorhome
    Most stabilizers are designed for travel trailers but they don't have exclusions for fitting motorhomes. With that said the Ultra Fab Power Twin II Electric Stabilizer part # UF39-941707 would be the best option as it has the widest frame width range of between 42 and 77 inches.

  • Can Lippert Components Stabilizer Jack Work On A 1987 Avion Travel Trailer?
    The Lippert Components High-Speed Power Stabilizer Jack - 30" Lift # LC298707 which includes the switch, wiring, and circuit breaker will stabilize but won't level. They will work on your 1987 Avion, but you would need to use leveling blocks like # A10-0920 as needed. The dual motor stabilizers like # UF39-941705 for 30 inch lift or # UF39-941707 for 22 inch lift are able to serve more as levelers because of their ability to individually adjust the height side to side.

  • Weight and Mounting Location of the Ultra-Fab Power Twin II Electric Stabilizer # UF39-941707
    I have confirmed with my contacts at Ultra-Fab and the weight of Ultra-Fab Power Twin II Electric Stabilizer for Trailers # UF39-941707 is 109 pounds. This stabilizer should be mounted directly to the frame of your trailer, and will work great along the rear of your trailer.

    In order to determine if the Ultra-Fab Power Twin II Electric Stabilizer for Trailers and RVs # UF39-941707 will fit your 2023 Airstream 30FB Bunk, you will just need to measure the width of your trailer frame. This electric stabilizer is designed to fit frame width's form 42" to 77" wide, and will require 24" of space on the frame for installation. If your trailer's frame falls into the above range, then this will work great. Finally, this electric stabilizer has a maximum weight capacity...

  • Choosing Between Ultra-Fab Power Twin II Electric Trailer Stabilizer With 22 or 30 Inch Lift
    The # UF39-941707 would only provide you with 2 inches of lift. If you wanted to carry some blocking with you to provide additional lift should you need it, this unit would work for you. However, since the # UF39-941705 with a 30 inch lift (which would provide a net gain of 10 inches) is the same price, there's no reason not to go with the additional lift if you should ever need it. Either stabilizer would be compatible with your 70 inch frame width.

  • Reducing Movement in a 5th Wheel Trailer While Parked
    Movement is normal when it isn't controlled. But when stabilization products are used then the movement can be reduced if not eliminated. You mentioned that you have tried things to correct this problem but did not mention what those things were so some of my recommendations may be something you have already tried. First we have to determine the nature of the movement. Is it side to side, front to back, or both? The front to back movement can result from slight movement at the trailer...

    The measurement you will need is from the outside of the frame. The Ultra-Fab Power Twin II Stabilizers # UF39-941707 can be adjusted between 48-77 inches wide. The mounting brackets will sit under the frame with the outside of the angled metal bracket resting on the outer edge of the frame.

  • Are the Switches of the Ultra-Fab Power Twin II Electric Stabilizer # UF39-941707 Waterproof
    The switches of the Ultra-Fab Power Twin II Electric Stabilizer # UF39-941707 are considered weather resistant meaning that as long as you don't submerge them under water they will hold up just fine under normal rain/snow situations.

  • What Is The Length Of The Ultra-Fab Twin II Stabilizer Mounting Bracket
    The mounting bracket for the Ultra-Fab Power Twin II Manual Stabilizer # UF39-941704 is approximately 35-3/8" in length. The frame height would dictate the amount of lift you would want but there are other factors to take into account. The placement of the stabilizer could lead you running into clearance issues when going up or down a steep hill so if you'd prefer to have as much clearance as possible then you'd go with the 22" # UF39-941707. The trade off is that you'd most likely have...

In addition, this has very specific mounting hole spacing on the frame of 68-11/16" from center-hole to center-hole.

  • How to Remove Stabilizer Jacks From a Travel Trailer
    There are only 2 ways to install a jack on a trailer; by bolting it on or by welding it on. A simple bolt-on installation could very well be removed at home but you will need to make sure that whatever jack you decide to replace it with is installed correctly for safety. If it is welded on you will need to find a qualified welder to remove the jacks.
